Broadband
High-speed transmission. The term is commonly used to refer to communications
lines or services at T1 rates (1.544 Mbps) and above. The speed threshold of
broadband is subjective and can be above or below T1. Some claim 45 Mbps is the
starting point of broadband. In every case however, it implies transmitting at higher
speeds than what was common before. Broadband often refers to Internet access
using cable modems and DSL, both of which deliver speeds above and below T1.
